Abstract

The invention relates to a manufacturing method of a tempered thin glass film. The method comprises the following steps: raw material glass is selected; a glass cutting machine is used for carrying out high-precision cutting upon the raw material glass according to corresponding length and width outline dimensions, such that rectangular glass sheets with various specifications are obtained; a laser cutting machine is used for carrying out button hole and earphone hole preliminary processing upon the obtained rectangular glass sheets; a numerical control machine tool is used for carrying out outline, button hole and earphone hole fine trimming upon the obtained glass sheets; the glass blank sheets obtained after fine trimming are subjected to tempering processing in a tempering furnace; an anti-bursting adhesive layer is adhered to the surfaces of the tempered glass sheets; and packaging is carried out. The manufacturing method provided by the invention has the advantages of reasonable design and short processing period. With the method, batch processing can be realized. The method and the product are safe and healthy, and the product has high quality.

Description

technical field [0001] The invention relates to a method for manufacturing a tempered thin glass film, in particular to a method for manufacturing a tempered thin glass film applied to a mobile phone. Background technique [0002] At present, the mobile phone film on the market is mainly plastic film (technical term is PET, PVC, PP, etc.). The advantages of plastic film are light, thin, and cheap; the disadvantage is that the light transmission is not good, it is easy to scratch (the hardness is 2-3H), the protective film is torn off, there is residual glue, fingerprints, oil stains are not easy to clean, and it cannot be effectively protected Damage to the screen caused by accidental collision or drop of the mobile phone. [0003] Tempered glass film is a new product after plastic film. It is the most effective high-tech product to protect mobile phone screens. For example, the Chinese patent application number 201320324269.6 discloses a tempered glass film, including temp...
